Depth estimation in half-space trees and feature range formulation for novelty detection

2026 · Information Sciences

Tree-based methods such as Isolation Forest (iForest) and Half-Space Trees (HS-Trees) are widely used for unsupervised anomaly detection due to their efficiency and scalability. However, the classical depth estimator $c(n)$, originally derived for iForest under …
